and leave, just remember that a court case will probably be taken out against you. Your name will be on "the list" and so even with your NOC you may not be allowed back in this country for a long long time. that's OK because we don't need people who knowingly break the law.
Better idea is to DO THE RIGHT THING and notify your landlord and work out a deal (get another renter) then you can leave knowing you are an honest person and you will sleep well at night.

DO THE RIGHT THING even if you are the only one who does.
